Embodiment 1
[0046] Centrifuge the gold nanorod solution obtained by the seed growth method (7000 rpm, 15 minutes), remove the supernatant, add CTAB (1-2 mM), repeat the centrifugation process three times, and disperse in the corresponding volume of CTAB (1-2 mM). .
[0047] The solution after growth was centrifuged to remove the supernatant, and the obtained gold nanorods were dispersed in 1.5 mM CTAB, and 5 mL was taken for subsequent experiments. NaOH (50 μL, 0.1M) solution and TEOS (volume fraction 20%) solution were prepared, 50 μL, 0.1M NaOH was added to the gold nanorods, and 15 μL TEOS (20%) solution was added every 1 h for a total of three additions. After 2 days of growth, centrifugation and washing, water and ethanol once, and finally dispersed into 2 mL of ethanol to obtain Au rod@SiO 2 solution.
[0048] 800 μL of OTMS chloroform solution (2.4%) (mass fraction) was added dropwise to 2 mL of Au rod@SiO 2 The solution (containing 80 μL NH4OH (32%)) was centrifuged after 24 h,...
Embodiment 2
[0053] The difference between this example and Example 1 is that the amount of the mixed solution injected by the syringe pump is different, so that the size and thickness of the prepared film are different.
[0054] Centrifuge the gold nanorod solution obtained by the seed growth method (7000rpm, 15 minutes), remove the supernatant, add CTAB (1-2mM), repeat the centrifugation process three times, and disperse in the corresponding volume of CTAB (1-2mM) .
[0055] The solution after growth was centrifuged to remove the supernatant, and the obtained gold nanorods were dispersed in 1.5 mM CTAB, and 5 mL was taken for subsequent experiments. NaOH (50 μL, 0.1M) solution and TEOS (volume fraction 20%) solution were prepared, 50 μL, 0.1M NaOH was added to the gold nanorods, and 15 μL TEOS (20%) solution was added every 1 h for a total of three additions. After 2 days of growth, centrifugation and washing, water and ethanol once, and finally dispersed into 2 mL of ethanol to obtain ...
Embodiment 3
[0061] The difference between this example and Example 1 is that the injection speed of the syringe pump is different, so the size and thickness of the films prepared with the same amount of mixed solution are different.
[0062] Centrifuge the gold nanorod solution obtained by the seed growth method (7000rpm, 15 minutes), remove the supernatant, add CTAB (1-2mM), repeat the centrifugation process three times, and disperse in the corresponding volume of CTAB (1-2mM) .
